Port of Savannah International Multi-Modal Connector

Astra is completing the $102 million rail expansion for the Port of Savannah’s International Multi-Modal Connector (IMMC) project at the Garden City Terminal near Savannah.

The civil infrastructure portion, which was completed on time in Summer 2019, consisted of providing soil improvements, earthwork, drainage and erosion control within and adjacent to the James D. Mason Intermodal Container Transfer Facility (ICTF), the realignment of a portion of Pipemakers Canal, installation of two (2) rail bridges across the realigned canal to accommodate future rail tracks, and the installation of a bridge across the canal for maintenance.

The rail infrastructure package consists of providing earthwork, drainage, erosion control, striping, asphalt pavement, crane rail and concrete runways for Rail Mounted Gantry (RMG) Cranes, compressed air system, utility work, lighting, fencing, electrical and communication work. Rail work includes installing turnouts, switches, track, and other track materials. Electrical work includes electrical power for the RMG cranes including directional drilling, electrical vaults, crane power anchor pits, and a crane electrical building.

Upon completion, the Mega Rail project will allow 10,000-foot trains to be loaded on terminal with containers double-stacked, and trains will increase capacity from 500,000 container lifts per year to 1 million.
